NAME¶
xfs_rtcp - XFS realtime copy command
SYNOPSIS¶
xfs_rtcp [
-e extsize ] [
-p ]
source ...
target
DESCRIPTION¶
xfs_rtcp copies a file to the realtime partition on an XFS filesystem. If
there is more than one
source and
target, the final argument
(the
target) must be a directory which already exists.
OPTIONS¶
- -e extsize
- Sets the extent size of the destination realtime file.
- -p
- Use if the size of the source file is not an even multiple
of the block size of the destination filesystem. When -p is
specified xfs_rtcp will pad the destination file to a size which is
an even multiple of the filesystem block size. This is necessary since the
realtime file is created using direct I/O and the minimum I/O is the
filesystem block size.
SEE ALSO¶
xfs(5),
mkfs.xfs(8),
mount(8).
CAVEATS¶
Currently, realtime partitions are not supported under the Linux version of XFS,
and use of a realtime partition
WILL CAUSE CORRUPTION on the data
partition. As such, this command is made available for curious
DEVELOPERS
ONLY at this point in time.
